Title: Optical head
Inventor: IKEDA YUUJI
IPC: G02B7/28
Filed: 1984-05-07
Abstract: PURPOSE:To attain the automatic focus control without using a cylindrical lens by setting a photodetector for photoelectric conversion at a position shifted from the condensing point of the reflected light sent from an information recording medium. CONSTITUTION:The reflected light sent from an information recording medium is condensed by a condenser means L and focused at a focal point F. At the same time, the beam spots having a certain distribution are formed on the photodetecting surface of a photodetecting element (consisting of photodetecting element units DA and DB) set before the point F. Then electric signals are produced by the units DA and DB in response to the received light quantity. In this case, the output difference between the DA and DB changes as shown in the figure as long as a lateral axis is defined as a distance between the point F and the photodetecting element. Therefore the automatic focus control is possible without using a cylindrical lens by driving an automatic focus control mechanism so as to obtain the constant output difference between both units DA and DB.

Title: Inductive radio system
Inventor: SHIMIZU KENICHI
IPC: H04B5/00
Filed: 1979-07-20
Abstract: PURPOSE:To increase the S/N of the inductive radio communication, by using the center line laid along the running path of the travelling object for the common flyback line and then providing the 8-shaped transmitting cross-type loop antenna and the receiving bar-type coil antenna including the magnetic core each to the travelling object. CONSTITUTION:Transmitter/receiver 1 of the fixed station is connected to parallel 3-wire-type inductive lines 3-5 along the locus of the travelling object. The travelling object incorporates bar-type antenna 5 including the magnetic core, receiver 6,  8- shaped cross-type loop antanna 7 and transmitter 8 each. The centers of antennas 5 and 7 are set right above inductive line 3 and then shift in parallel to the  surfaces of inductive lines 2-4. When the high frequency current is flowed to antenna 7 from transmitter 8, the magnetic flux generated at antenna 7 is coupled well to  the inductive line and is not coupled to antenna 5. And with supply of the transmitting current to the inductive line from transmitter/receiver 1, the horizontal  magnetic flux sent from line 3 crossing antenna 5 is strengthened by the magnetic  fluxes from lines 2 and 4. As a result, not only the transmitting power of the travelling object but the receiving level can be increased, thus enhancing the quality of  communication.

Abstract: PURPOSE:To lighten the work of maintaining an electric power unit of a cordless X-ray apparatus for doctor's round visits by supplying a d.c. output to an inverter so as to be converted into a three-phase a.c. of desired frequency, and then changing over a switch so that the three-phase a.c. on the one hand may be supplied to a rotating -anode drive motor and on the other hand may be supplied to a traveling drive- motor. CONSTITUTION:When a cordless X-ray apparatus for a doctor's round visits is moved, an operator connects a selecting switch 11 to the side of travel. Thus a control unit 8 operates a relay 9 so that a contact 10 may be connected to the side of a traveling drive-motor and also an inverter 7 may output three-phase a.c. power. When the X-ray appratus for a doctor's round visits is moved to a desired position in order to initiate the exposure of X-ray, the operator changes over the switch 11 to the side of a rotating anode from the side of travel. The control unit 8 thus operates the relay 9 so that the contact 10 may be connected to the side of a rotating-anode drive motor. Thus there may be no need to install electric power units separately for the traveling drive- motor and the rotating-anode drive motor, and the work of maintaining the electric power unit of the cordless X-ray plant for a doctor's round visits is lightened because a three-pulse induction motor is employed.

Title: Synchronizing connector circuit
Inventor: YAMAZAKI AKIRA
IPC: H04N5/08
Filed: 1987-04-15
Abstract: PURPOSE:To eliminate noise from a synchronizing signal by providing a noise elimination circuit which is driven by a clock signal generated by an oscillator. CONSTITUTION:A synchronizing separator aignal (b) is inverted of its polarity by an inverter 10, and supplied as an inverted synchronizing signal b' to the serial-in and load terminals of a shift register 11. Also, a clock signal (d) which is an output signal from the oscillator 5 is supplied to the clock input of the shift register 11. Since the width of noise superposed on the synchronizing separator signal (b) is considerably narrow in comparison to that of a synchronizing signal, the noise can be eliminated by setting the suitable times of clock shifting. In such a way, the noise is eliminated by using a clock signal from the oscillator even if the noise is superposed on the synchronizing separator signal, as a result, a stable synchronizing connector circuit can be obtained.

Title: Picture recording device
Inventor: MORITA NAOYUKI
IPC: B65H1/26
Filed: 1987-04-15
Abstract: PURPOSE:To use a sensitized material with high efficiency, by providing a cutter which cuts a sensitized material located between a magazine and an exposing part and a light shield part which shields the sensitized material, located between the cutter and the magazine, from external light. CONSTITUTION:Since a portion between a rotary cover and a magazine 14 is shielded from light by means of a light shield plate 98 and a portion between the magazine 14 and a moving platform 64 is shielded from light by means of a light shield plate 120, a rotary cover 88 brings the moving locus of a sensitized material 16 between the magazine 14 and a cutter 18 into a light shield state. Thus, a most of the sensitized material 16 pulled off from the magazine 14 is positioned in the rotary cover 88 and is brought into a state to be shielded from light, a photographic fog is prevented from production. Though there is a possibility that the cut tip part of the sensitized material 16, present between the rotary cover 88 and the cutter 18, is brought into a slight fog state due to release of the cover plate of a machine bed, there is no problem since this part is a part being out of a picture. This constitution eliminates a control means to discharge a fog part, and enables the effective use of the sensitized material 16.

Title: Television receiver
Inventor: ISHII SATOYUKI
IPC: H04N7/01
Filed: 1994-04-28
Abstract: PURPOSE:To allow the television receiver to surely discriminate the broadcast system and to set an optimum mode depending on the broadcast system. CONSTITUTION:An input video signal is converted into R, G, B signals by an NTSC decoder 2. An aspect ratio discrimination circuit 3 uses an identification signal to discriminate an aspect ratio of the input video signal and to detect the presence of a non-picture part thereby discriminating the aspect ratio of the input video signal. Thus, the S/N of the input video signal is defective or a ghost failure is caused or the video signal is a signal reproduced from a VTR or the like, the aspect ratio is surely discriminated. When the signal of a 2nd generation EDTV system is received by a discrimination output of the aspect ratio, a masking circuit 5 masks a non-picture part of an output of an NTSC decoder 2 and provides the result to a display device 6. Thus, the optimum picture mode in response to the system of the input video signal is set.
